I got 2 straight run Gold Laced Wyandotte chicks from Tsc last night. I wanted to attempt to feather sex them and pick out 2 females, however they would not let me do that. I noticed some chicks had brighter butt stripes and chicks with lighter more dull butt stripes. So I told her to give me 2 of the dull colored butt stripe chicks. So I guess my question is if color of the butt stripes is an indicator of sex of the chicks.
